[Effect of radiation on the structural state of erythrocyte membranes]

Using fluorescent probe 4-(n-dimethyl-aminostyryl)-1-methyl-pyridine (DSM) the effect of electrons with the energy 5 MeV on the structure of erythrocyte membrane has been investigated. It was found that in the irradiated erythrocyte ghosts the number of DSM binding sites increases. Irradiation was suggested to increase the negative surface charge of the erythrocyte membrane.
